You can argue this is good or bad, but the bottom line is Ash and Kali being able to crack Mira windows, Mira becomes really weak.
Just about every game has and Ash and she will even be able to crack electrified Mirrors. Unless you have a Jager or Wamai on your team, Mira will be worthless.
Why are they doing that? I wanna know who was asking for a Mira nerf
I mean, she is banned a lot and a little down tuning is probably necessary (and this is coming from someone that uses her a lot). However, using the most picked player in the game is a huge hit. Like Ash needs any buffs. I say, let electrified reinforced walls deny Ash charges and that would be a balanced nerf to Mira.
